Definitions
- This invention relates to application of microbiocides and surfactants to poultry.
- Poultry processing is an area in which microbiological control is of vital importance. By the very nature of the processing involved, there are numerous opportunities for the poultry to be exposed to various pathogens. Contamination of poultry meat products with various pathogens such as species of Listeria, Escherichia, Salmonella, Campylobacter, and others, is a problem that has existed for many years.
- This invention provides combinations of microbiocides and surfactants that have enhanced microbiocidal efficacy, especially against Campylobacter.
- the increased efficacy allows greater microbiocidal control while using less microbiocide.

In other instances, it may be preferred to store the carcass under refrigeration on site, and later, when it is desired to package the carcass for sale or shipment, this can be done without further treatment.
- the microbiocidal composition of this invention is applied to an unopened defeathered poultry carcass, to the eviscerated carcass during inside-outside washing of the carcass, to the eviscerated poultry carcass in the chill tank, and optionally but preferably, to the carcass after removal from the chill tank and before packaging for storage or shipment.
- free bromine is used to describe the free or relatively fast-reacting forms of bromine oxidants present in aqueous solutions. In the case of the microbiocides used in the practice of this invention, total bromine is the same as active bromine.
- ppm Cl 2 total chlorine values
- ppm Br 2 total bromine values
- the given concentration for "free chlorine” or “total chlorine” in terms of ppm Cl 2 is multiplied by 2.25, the molecular weight ratio of Br 2 to Cl 2 .
- the given concentration of halogen is reported as Br 2 , it can be converted to a Cl 2 value by dividing by 2.25, the molecular weight ratio of Cl 2 to Br 2 .
- bromine residual refers to the amount of bromine species present in the treated water available for disinfection. Residuals can be determined as either “free” or “total” depending upon the analytical test method employed. In the present case, the numerical values for bromine residual have been given herein on a free bromine basis. Such values can be monitored by use of the analytical procedure for "free chlorine” given below. However if desired, the bromine residual could be monitored on a “total bromine” basis by using the analytical procedure for "total chlorine” given below. In either case the numerical values obtained are in terms of chlorine and thus such values are multiplied by 2.25 to obtain the corresponding bromine values.
- Suitable methods for determining "bromine residual” are known and reported in the literature. See for example, Standard Methods For the Examination of Water and Wastewater, 18th Edition, 1992, from American Public Health Association, 1015 Fifteenth Street, NW, Washington, DC 20005 (ISBN 0-87553-207-1), pages 4-36 and 4-37; Hach Water Analysis Handbook, Third Edition, 1997, by Hach Company, Loveland Colorado, especially pages 1206 and 1207; and Handbook of Industrial Water Conditioning, 7th edition, Betz Laboratories, Inc., Trevose, PA 19047 (Library of Congress Catalog Card Number: 76-27257), 1976, pages 24-29. While these references typically refer to "chlorine residual", the same techniques are used for determining "bromine residual", by taking into account the higher atomic weight of bromine as compared to chlorine.
- Active halogen content is determinable by use of conventional starch-iodine titration.
- a standard test for determination of low levels of active halogen is known as the DPD test and is based on classical test procedures devised by Palin in 1974. See A. T. Palin, "Analytical Control of Water Disinfection With Special Reference to Differential DPD Methods For Chlorine, Chlorine Dioxide, Bromine, Iodine and Ozone", J. Inst. Water Eng., 1974, 28, 139. While there are various modernized versions of the Palin procedures, the recommended version of the test is fully described in Hach Water Analysis Handbook, 3rd edition, copyright 1997.
- total chlorine ⁇ i.e., active chlorine
- Method 8167 appearing on page 379
- the “total chlorine” test involves introducing to the dilute water sample containing active halogen, a powder comprising DPD indicator powder, ⁇ i.e., ⁇ , ⁇ '- diethyldiphenylenediamine, KI, and a buffer).
- the active halogen species present react(s) with KI to yield iodine species which turn the DPD indicator to red/pink.
- the intensity of the coloration depends upon the concentration of "total chlorine” species (i.e., active chlorine") present in the sample.
- This intensity is measured by a colorimeter calibrated to transform the intensity reading into a "total chlorine" value in terms of mg/L Cl 2 . If the active halogen present is active bromine, the result in terms of mg/L Cl 2 is multiplied by 2.25 to express the result in terms of mg/L Br 2 of active bromine.
- the water sample should be analyzed within a few minutes of being taken, and preferably immediately upon being taken.
- Hach Method 8167 for testing the amount of species present in the water sample which respond to the "total chlorine” test involves use of the Hach Model DR 2010 colorimeter. The stored program number for chlorine determinations is recalled by keying in "80" on the keyboard, followed by setting the absorbance wavelength to 530 nm by rotating the dial on the side of the instrument. Two identical sample cells are filled to the 25 mL mark with the water under investigation. One of the cells is arbitrarily chosen to be the blank. To the second cell, the contents of a DPD Total Chlorine Powder Pillow are added. This is shaken for 10-20 seconds to mix, as the development of a pink-red color indicates the presence of species in the water which respond positively to the DPD "total chlorine" test reagent.
- the SHIFT TIMER keys are depressed to commence a three minute reaction time. After three minutes the instrument beeps to signal the reaction is complete. The blank sample cell is admitted to the sample compartment of the Hach Model DR 2010, and the shield is closed to prevent stray light effects. Then the ZERO key is depressed. After a few seconds, the display registers 0.00 mg/L Cl 2 . Then, the blank sample cell used to zero the instrument is removed from the cell compartment of the Hach Model DR 2010 and replaced with the test sample to which the DPD "total chlorine" test reagent was added. The light shield is then closed as was done for the blank, and the READ key is depressed.
- One method for measuring free chlorine is the Hach Method 8021. This tests for the amount of species present in the water sample which respond to the "free chlorine" test. This test involves the use of the Hach Model DR 2010 colorimeter.
- the stored program number for chlorine determinations is recalled by keying in "80" on the keyboard, followed by setting the absorbance wavelength to 530 nm by rotating the dial on the side of the instrument.
- Two identical sample cells are filled to the 25 mL mark with the water under investigation.
- One of the cells is arbitrarily chosen to be the blank.
- the blank sample cell is admitted to the sample compartment of the Hach Model DR 2010, and the shield is closed to prevent stray light effects.
- the ZERO key is depressed.
- the display registers 0.00 mg/L Cl 2 .
- the blank sample cell used to zero the instrument is removed from the cell compartment of the Hach Model DR 2010.
- the contents of a DPD Free Chlorine Powder Pillow are added.
